[Help KWin] Update screen when Dim Inactive Effect Configuration Changes

Today I have a very easy coding task. In fact writing this blog post is more work than fixing it myself :-) I thought this is a wonderful task for anyone who wants to start contributing to KWin as a developer.

The task is documented in Bug 308283. If you want to work on it, just assign the bug to yourself, once you are finished either create a review request or upload a git format-patch to the bug report (git format-patch so that we can easily include it).

Please work on top of the KDE/4.9 branch as that should go into the next bug fix release and master and branch have diverged.
